Peter,

I had no idea either but a very simple google search turned up this:

http://www.microsoft.com/whdc/system/pnppwr/wmi/default.mspx

Not positive that's it, but it wouldn't take much to find out.

>>Peter, you can try using WMI to do this:

>>loLocator			= createObject("wbemScripting.SwbemLocator")
>>loWMI				= loLocator.ConnectServer()
>>
>>loMonitors			= loWMI.ExecQuery('Select * from Win32_DesktopMonitor')
>>
>>for each loMonitor in loMonitors
>>	? loMonitor.DeviceID, loMonitor.ScreenWidth, loMonitor.ScreenHeight
>>endfor
>>

>>I do not have 2 monitors to test, so let me know if I got the correct class :)
